“…For the determination of the test organism's susceptibility, 10 7 colony-forming units CFU mL sterile saline overnight cultured of bacteria in Mueller-Hinton broth (MHB) (Oxoid, England) was collected, transferred, and treated with different concentrations of the samples (i.e. 6.25, 12.5, and 25 mg/ml) on a Petri plate incubated overnight (Hi-media) in 37°C for 18 h. The diameter of the inhibited area around each well was considered as an antibacterial activity (Ravikumar et al 2012). Blank or negative Control, 100 µL of DMSO was used.…”

The present study reported a green approach for sonochemical-assisted synthesis (SAS) of cadmium selenide nanoparticles (CdSe NPs) by using the aqueous extract of Leontice Leontopetalum plant. The aqueous extract was obtained by ultrasonic- assisted extraction (UAE; 15 min, 50°C) and microwave- assisted extraction (MAE; 15 min, 180, and 270 W) as two instrumental techniques. Next, the as-prepared aqueous extracts were used in a plant-mediated synthetic approach for the synthesis of CdSe NPs by applying the SAS technique. The synthesized samples were characterized via different techniques; including transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), ultraviolet-visible absorption; photoluminescence, and Fourier transform infrared spectroscopy. The average particle size of the prepared CdSe NPs was estimated below 50 nm. UV-Vis absorption and fluorescence techniques indicate a wide absorption band around 360–420 nm and an intense emission peak around 460 nm, respectively. After green synthesis and characterization, antimicrobial, antioxidant, and antifungal properties of the aqueous plant extracts as well as their corresponded CdSe NPs were evaluated by different assays, comparatively. Moreover, the genotoxicity and toxicity potential of the samples were investigated. The results indicate the significant antimicrobial activity of the extracts as well as the CdSe NPs, with the negligible toxicity and genotoxicity impacts.

“…Gold nanoparticles have been investigated as an antimicrobial agent to inhibit the growth of common, waterborne, pathogens Escherichia coli and Salmonella typhi , which are developing resistance to common bactericides [ 30 ]. In aquaculture, several studies have been carried out to investigate gold nanoparticles as antimicrobial drugs [ 31 – 33 ].…”

In vitro antimicrosporidial activity of gold nanoparticles against Heterosporis saurida

et al. 2016

BackgroundWorldwide, there is a need to expand the number of drugs available to treat parasitic infections in aquaculture. One of the new materials being tested is metal nanoparticles, which have unique chemical and physical characteristics owing to their extremely small size and high surface area to volume ratio. We examined the effectiveness of gold nanoparticles against the microsporidian parasite Heterosporis saurida, which causes severe economic losses in lizard fish, Saurida undosquamis aquaculture.ResultsWe synthesized gold nanoparticles by chemical reduction of tetrachloroauric acid as a metal precursor. We assessed the antimicrosporidial efficacy of the nanoparticles against H. saurida using an in vitro screening approach, which we had developed previously using the eel kidney cell line EK-1. The number of H. saurida spores produced in EK-1 cells was reduced in a proportional manner to the dosage of gold nanoparticles administered. A cell metabolic activity test (MTT) indicated that the gold nanoparticles did not appear to be toxic to the host cells.ConclusionsGold nanoparticles can act as an effective antimicrosporidial agent and hold promise to reduce disease in lizardfish aquaculture. Metal nanoparticles should be considered as an alternate choice for development of new antimicrosporidial drugs to combat disease problems in aquaculture.

“…Antibacterial property of metal nanoparticles against Gram-positive bacteria is demonstrated to be higher compared to Gram-negative bacteria (Premanathan et al, 2011;Ravikumar et al, 2012;Azam et al, 2012;Zain et al, 2014) . This might be because the cell-wall structure of Gram-negative bacteria is more complex than that of Gram-positive bacteria (Zain et al, 2014) .…”

“…There are just few studies about inactivation of V. parahaemolyticus using metal nanoparticles. Ravikumar et al (2012) firstly investigated the effect of five commercial nanoparticles such as Al 2 O 3 , Fe 3 O 4 , CeO 2 , ZrO 2 , and MgO on V. parahaemolyticus. Among the five nanoparticles, only MgO nanoparticles showed antibacterial activity against V. parahaemolyticus.…”

“…However, studies investigating antibacterial activity of copper nanoparticles against shrimp pathogenic bacteria especially V. parahaemolyticus are very limited. There are just a few reports about inactivation of V. parahaemolyticus using metal nanoparticles other than CuNPs (Ravikumar et al, 2012;Kandasamy et al, 2013;Zarei et al, 2014) . The current study is considered as the first report on inactivation of V. parahaemolyticus using copper nanoparticles.…”

The Mekong Delta, Vietnam has traditionally been the major region of aqua produce accounting for over 52% of national aqua crop, and 65% of aqua export. In 2018, the aqua export value was over US$ 8.8 billion dollars, to which export of shrimp contributed 45%. However, pathogen infections directly influence the production and value-added contribution of shrimp in the region. The most common and serious infection is Early Mortality Syndrome (EMS) (or Acute Hepatopancreatic Necrosis Syndrome -AHPNS) caused by Vibrio parahaemolyticus. It has caused a severe economic loss for shrimp industry in various countries such as Vietnam (Oanh et al., 2013) , Malaysia (Kua et al., 2016) , Thailand (Joshi et al., 2014 , etc.Copper nanoparticles (CuNPs) have attracted attention of researchers in recent years owing to their low-cost, abundance and remarkable antimicrobial activity. Previous studies have reported antimicrobial properties of CuNPs against Micrococcus luteus,
